AUTOMOBILE-LIGHT Ann DIMMER.

Application filed July 31,

To all whom it may concern:

Be it known that 1, MARK Cox, a citizen of the United States, and a resident of Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Automobile-Light and Dimmer, of which the following is a specification.

The object of my invention is to provide an automobile lamp of simple, durable and inexpensive construction.

More particularly it is my object to provide an automobile lamp of such type that the rays of light may be directed in different directions, and with different intensities, and difierent diffusions on the road in front of a car.

I With these and other objects in view my invention consists in the construction, arrangement and combination of the varlous parts of the device, whereby the ObJGCtS contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure 1 shows a side elevation of a lamp embodying my invention, parts being broken away and parts being shown in. cross section.

Igig. 2 shows a front elevation of the same; an

Fig. 3 shows a perspective view of the lamp, illustrating the manner in which it is mounted.

In the accompanying drawings I have used the reference numeral 10 to indicate generally the casing of my improved lamp, which is tubular in form and is longitudinally elongated, as-illustrated in Figs. 1 and 3.

The casing 10 is closed at its end 11 and has at its other end a lens 12, the upper portion of which is made opaque at 13 in any desired way.

In the upper half of the casing 10 on the interior thereof is a channel-shaped reflector 14.

Mounted in the reflector 14 near the lens 21 is an electric lamp 15, and mounted in the rear part of the reflector 14 is another electric lamp 16.

The lamp casing 10 has on its opposite Specification of Letters Patent. v Patented Feb. 11,1919.

sides laterally extending spindles 17 which '.are designed to bemounted in thelarms of a bracket 18 which is supported on a frame 19.

The bracket 18 has at its rear end an outwardly extending portion 20 provided with an elongated slot 21.

On the" lamp casing is a rearwardly extending pin 22- extended through the slot 21 and having nuts 23am 24 on opposite sides of said slot. By loosening the nut 23 the rear endof the lamp may be raised or lowered for directing the rays of light in different directions. 7

In the practical 'use of a lamp of this kind, I have found that by using the two lights in the same lamp casing and elongating the lamp casing as here shown, there can be secured such a variety in the directing of the rays and the difi'usion of them as to serve the purpose of a dimmer and a proper light very satisfactorily, and also to secure the kind of light desired for a variety of circumstances.

It is obvious that the lamp may be tilted as may be desired for still further increasing its range of use.

It will'be noted that if the rear lamp 16 only is lighted, a long narrow light will be directed-ahead of the machine, while if the forward lamp 15 only is lighted there will be a comparatively wide sheet of light directed ahead of the machine and downwardly.

Some changes may be madein the construction and arrangement of the parts of my improved lamp without departing from the essential features and. purposes of my invention, and it is my intention to cover by my application any modified forms of structure or use' of mechanical equivalents which may be reasonably included within the scope of my claims.

I claim as my invention:

1. In a device of the class described, a lamp having a casing substantially elongated, a reflector in the upper portion of said casing, a lens at one end of said casing, a light device in said casing adjacent to the reflector and adjacent to the lens, a second lamp in said casing and adjacent to the other end of the casing.

2. In a device of the class described, a

lamp having a casing substantia11y elon- 5 gated, a reflector in the upper portion of said casing, a hght device 1n s a1 a lens at d casing adjacent to the one end of said casing,

reflector and adjacent to the'lens, a second lamp in said casing adjacent to the reflector and adjacent to the other end of the casing, 10 and means for pivotally supporting said casing.
